Specific embodiment
The utility model is described in further detail below in conjunction with attached drawing.
Embodiment: a kind of dust-proof coupler, as depicted in figs. 1 and 2, including machine body 1, the outside of machine body 1
Several connectors 11 are bolted on wall, the outer sheath of connector 11 is equipped with dust cover 2,2 open end of dust cover
Bottom and the lateral wall of machine body 1 abut against.The setting of dust cover 2 reduces the opening of external dust intrusion connector 11,
Reduce influence of the dust to the utility model efficiency of transmission.
As shown in Figure 1, offering anti-sliding burr 23 on the lateral wall of dust cover 2.Anti- sliding burr 23 increases dust cover 2
Surface roughness, therefore operator is when grabbing dust cover 2, it is more firm.
As shown in Figure 1, the two sides of dust cover 2 are welded with link block 21, the lower surface of link block 21 is connected to machine body 1
Lateral wall.The setting of link block 21 increases the contact area between dust cover 2 and machine body 1, so that connector 11 exists
It is more not easily to fall off when being protected using dust cover 2, to enhance the stability of the utility model.
As shown in figure 4, the lower surface of link block 21 is respectively welded locating rod 211, it is provided on the lateral wall of machine body 1
Location hole 12, locating rod 211 are embedded in location hole 12.When using dust cover 2, dust cover 2 is easy around 11 turns of connector
It is dynamic, to reduce dust-proof effect, therefore the setting of locating rod 211, by being embedded locating rod 211 in location hole 12, limit
The rotation of dust cover 2 processed, to improve the dust-proof effect of the utility model.
As shown in figure 3, being provided with the through-hole 22 communicated in link block 21 and locating rod 211, locking screw is provided in through-hole 22
Bolt 3, clamping screw 3 are threaded through through-hole 22 and are threadedly connected to the lateral wall of machine body 1.The setting of clamping screw 3, so that
Connection between dust cover 2 and machine body 1 more fastens, and such dust cover 2 better plays dust-proof effect.When needs make
When with machine body 1, dust cover 2 can be removed by backing out clamping screw 3, so operation is relatively simple.
As shown in figure 3, through-hole 22 offers guiding chamfering 221 far from one end of machine body 1.When use clamping screw 3
When fixed dust cover 2, guiding chamfering 221 is opened up so that operator is without taking a significant amount of time accurately interspersed clamping screw 3,
Clamping screw 3 can be rapidly inserted into through-hole 22 by operator under the action of being oriented to chamfering 221, to improve practical
Novel service efficiency.
As shown in Figure 1, being provided with friction lines 31 at the grip of clamping screw 3.It through-hole 22 and is revolved when clamping screw 3 to be inserted into
When tight clamping screw 3, due to the setting for the lines 31 that rubs, the frictional force of operator's finger Yu clamping screw 3 is increased, so
Operator is more convenient quick when using clamping screw 3, to further improve the service efficiency of the utility model.
As shown in figure 3, location hole 12 offers lead-in chamfered 121 close to the upper end of link block 21.Operator is installing
When dust cover 2, due to locating rod 211 and location hole 12 is smaller and sight back to operator, so locating rod 211 is being embedded
When entering in location hole 12, it is difficult fast aligning, to influence the installation speed of dust cover 2.Therefore, the setting of lead-in chamfered 121,
The installation speed of dust cover 2 is improved, to improve the service efficiency of the utility model.
As shown in figure 3, link block 21 and dust cover 2 are close to the side of machine body 1, fixed splicing has rubber protection pad 4.
Since rubber protection pad 4 is soft and frictional force with higher, so when locking dust cover 2 using clamping screw 3, rubber
Glue neonychium 4 reduces dust cover 2 and machine body 1 directly compresses and caused by abrasion, and higher frictional resistance to prevent
The installation of dust hood 2 is more stable, therefore improves the service life of the utility model.
Specific implementation process: being directed at and be inserted into location hole 12 for the locating rod 211 of the lower section of dust cover 2 so that dust cover 2 with
Machine body 1 abuts against.Clamping screw 3 is aligned and is inserted into through-hole 22, clamping screw 3 is rotated further by and makes dust cover 2 and machine
Device ontology 1 is securely seated between together.With this, the installation of dust cover 2 is completed.
Since each connector 11 in machine body 1 is arranged with dust cover 2, and the setting of dust cover 2 has obstructed the external world
Dust directly invades connector 11, and in this way under the protection of dust cover 2, the utility model remains optimal spare shape
State, to improve the service efficiency of the utility model.
This specific embodiment is only the explanation to the utility model, is not limitations of the present invention, ability
Field technique personnel can according to need the modification that not creative contribution is made to the present embodiment after reading this specification, but
As long as all by the protection of Patent Law in the scope of the claims of the utility model.
